Question

The equation below represents Function A and the graph represents Function B:

Function A

f(x) = 6x − 1

Function B ( image )



Which equation best compares the slopes of the two functions?

a) Slope of Function B = 2 x Slope of Function A.
b) Slope of Function A = Slope of Function B
c) Slope of Function A = 2 x Slope of Function B
d) Slope of Function B = − Slope of Function A

Answer 1

C

Explanation:

I took the test and got a 100%

Answer 2

The slope of function A is the coefficient of x, which is 6.

The slope of function B is the rise divided by the run, which is 3/1 = 3.

The appropriate choice is ...

... c) Slope of Function A = 2×Slope of Function B
